On April 3, 1989, 22-year-old Chip Flynn was shot to death in a Central Florida orange grove. Soon after, police arrested Crosley Green, a black man recently released from prison on drug charges. On Sept. 5, 1990, all all-white jury convicted Green... (more), then 32, of first-degree murder. He was sentenced to death. Ever since, he has been on death row. Last year five prominent private detectives got together to try to exonerate Green. They believe he is innocent. 48 Hours Correspondent Erin Moriarty followed them as they revisited crime scenes, reinterviewed witnesses and reinterpreted evidence, in an effort to save Green's life.
